Mobile device-based data verification subsystem is developed using mobile GIS, remote sensing dynamic monitoring information system of mining is constructed, and "timely release, fast handling and timely feedback" rapid response mechanism of remote sensing dynamic monitoring is implemented. 1. INTRODUCTION Hongsong,2007). After achieving success, Shandong Province has carried out multi-round monitoring in 93 Mineral resources are an important material basis of China's counties (cities and districts) of the province successively. social and economic development. For a long time, Through monitoring and field verification statistics, the development and utilization of mineral resources have been distribution status and property of unlicensed mining and relatively extensive in China due to various reasons. There patch mining in the monitoring zone have been identified, are still some prominent problems exist in management of and cross-border mining, mining instead of exploration and mineral resources development, and mine exploitation has other illegal phenomena are found timely, thereby providing caused a serious waste. The Party Central Committee and the comprehensive and accurate first-hand information and basis State Council attach importance to the protection and rational for mining administration and management departments' development and utilization of mineral resources, and have management and law enforcement. made comprehensive efforts to rectify and standardize the order of mineral resources development. Compared with 1.2 Existing Problems conventional means, remote sensing technology performs detection in a high-altitude aerial view way, which can Shandong Province has carried out five rounds of remote surmount traffic barriers and visual limits; remote sensing sensing dynamic monitoring in open pit mines in the entire dynamic monitoring can quickly and duly provide relevant province's bedrock areas, and has accumulated a wealth of departments with timely and objective basic data and experience. However, the intermittent uncertainty of illegal decision-making basis for exercise of governmental functions mining, the variability of patch mining, and the "guerrilla" and rectification of mining development order, can enhance character and repeatability of covert mining have led to the the high-tech content in supervision and management, and following problems in the remote sensing dynamic can improve the efficiency of supervision and management monitoring work: and the quality of management; meanwhile, mineral i) Untimely release of remote sensing monitoring results. resources exploitation remote sensing monitoring has also Due to the large scope of monitoring area, remote sensing formed a relatively mature technological roadmap image processing and patch interpretation workloads are (Datcu,2003; Nie Hongfeng,2007; Chen Weitao,2009; Nan large. As remote sensing monitoring results are distributed to Junxiang,2012; Wang Yonggang,2008). Shandong Province cities and counties in the traditional way of map printing, has been carrying out mining remote sensing monitoring pilot suspected illegal patches cannot be found and verified timely. work since 2006 to provide scientific and reliable information ii) The poor quality of data verification. for mineral resources regulation utilizing the advanced, broad In accordance with the existing mining administration and and time-sensitive characteristics of remote sensing management system, suspected illegal patch mining shall be technology. At present, remote sensing dynamic monitoring verified and handled by local mining administration and mechanism has been formed for open pit mines in Shandong management authorities. In the actual practice, superior Province's bedrock areas, which provides land and resources authorities can not verify the authenticity and accuracy of departments with scientific law enforcement basis for the data reported by cities and counties due to the low development and management of mineral resources, as well verification quality of primary-level staff and other problems, as low-cost, fast and efficient fight against illegal mining leading to ineffective supervision of local land and resources behavior. departments, thus resulting in mine mismanagement. Based on the above background, this paper presents ideas 1.1 Introduction of Mineral Resources Remote Sensing such as implementation of rapid monitoring data release by Dynamic Monitoring Project in Shandong Province service mode and improvement of field verification data quality through the practice of remote sensing dynamic In 2006, in Linyi City, Shandong Province launched a pilot monitoring project in Shandong Province's bedrock areas, remote sensing dynamic monitoring project in Linyi City's and completes the development of mining remote sensing Lanling County (formerly Cangshan County)( Cao dynamic monitoring information system. This contribution has been peer-reviewed. https://doi.org/10.5194/isprs-archives-XLII-2-W7-893-2017 | © Authors 2017.

DESIGN IDEAS shown in Figure 2. 2.1 Quick Release of Monitoring Data 3. OVERALL SYSTEM FRAMEWORK The remote sensing dynamic monitoring project of open pit Based on the above ideas, remote sensing dynamic mines in Shandong Province's bedrock areas has a large monitoring and management information system of mining is monitoring range, which involves 13 cities. Monitoring data built using service-oriented architecture (SOA), as shown in include monitoring images and interpretation patches. Figure 3. Monitoring images are sliced in accordance with Platform for geo-information common services Data specification for electronic map(National Geomatics Center of China,2011), user layer Internet smart and published as OGC WMTS services; while interpretation two dimensional map three dimensional map patches are published as OGC WMS/WFS services.

Overall architecture diagram of system Technology The system is divided into runtime support layer, data layer, interpretation patches application system layer and user layer. Networks as well as software and hardware environments supporting system auxiliary GPS positioning running are constructed relying on the land and resources field investigation intranet and the Internet. Mineral rights database and remote information reporting Completing spot survey failure sensing dynamic monitoring database are built using Oracle success and ArcSDE software. Subsystems of map management, data publication, assistant management, remote sensing Take pictures to check Coordinate information storage failure monitoring and supervision, mobile data verification and success system management are created using the online geographic Image watermark information services provided on the Geographic Information Public Service Platform of Shandong Province. Users use the failure Artificial copy Image upload uploaded system via B/S access or mobile terminals, and smart device- success based verification and reporting mechanism is established. server-side validation All of these help establish and improve the normalized failure information success mineral exploitation supervision system of Shandong Province with timely discovery, clear responsibility, powerful end handling and effective supervision features.
